Appncauon mea may 1a,

This invention relates to improvements` in the rotor member of a rotarydisintegrating apparatus and consists ofthe matters hereinafterdescribed and more particularly pointed out in the appended claims.

The invention relates to that type of disn integrating apparatus offamiliar use in gas washing apparatus, in which the disintegratorelements consist of circular rows of fixed rods or bars alternating and`interlaced with like rows of`similar bars carried by a rotary discinterposed between the supports of the fixed bars. f i

The object of .the invention is to provide a novel and improvedconstruction of the rotor member including the disintegrating rods orbars carried thereby, which is capable of withstanding the severebending stresses and vibratory strains resulting from the high speed ofrotation (as much as 18,000 feetor more per minute in the arcuate pathof the outer row) of the disintegrator rods or bars.

Another object of the invention is to provide a construction having theadvantages described, which is cheapand economical to manufacture andwhich is capable `of ready and easy assembly.

These and other advantages of the invention will appear more clearly asI proceed with my specification.

In the drawings n Figure 1 is a side elevation of the rotor member of arotary disintegrating apparatus of the kind referred to made inaccordance with my invention. Y

Figure 2 is a section of the same in a plane indicated by the line 2-2of Figure 1.

Figure 3 is a sectional view in a plane indicated by the line SH3 ofYFigure 2.

Figure 4 is a fragmentary, sectional view on an enlarged scale showingthe connection of one of the disintegrator elements to a ring includedin the assembly of the rotor.

Referring now to that embodimentof the invention illustrated in thedrawings 10 indicates the rotor member of a rotary disintegratingapparatus, such, for example, as that used for washing gas, wherein myinvention is of special value on account of the. high speeds attained bysaid rotor member. Said rotor consists of a shaft'll; of a disc 12concentric therewith and `rigidly fixed made at comparatively smallcost.

thereon f between hubs 13, i 13; of radially spacedycircular rows ofdisintegrator elements 14, 15 extending to either side of the disc` 12carried nearthe periphery thereo; and" ofringsy 16, 17 carried by theends of said disintegrating e1ements.` y

Each disintegrator element 14, 15, which is preferablya round rod, isprovided with a radial boss 18 near its middle adapted forflatengagement on 4one side with the proxi` `mateface of' the disc 12,said rod onone side of` the boss beingr of aglength to extend to andthrough theonetof therings`16,l` 17 withwhich it is associated on thatside of the disc with which the boss is engaged, and the other sidebeingof a length in addition equal to the thickness ofthe disc. The rodsare placed with the bosses 18 of .alternate rods in engagement withopposite sides of the disc 12, as clearly shown in the draw?` ings. Eachrod has reduced ends 19 engaged in holes 19a in the ring with shoulders19?,engaged against the proximate ,face of the ring 16 or 17) with whichit is asso`- ciated. AThe A'outside ends of the said holes 19 haveconical recesses into which theends of the rods are riveted to provideconical heads 19.

By the construction described, each rod 14 or 15 in a row rigidlyconnects the associated pair of rings 16 or 17 against lateral movementin either direction and each pair 4oi. adjacent rods, by means of theiropposed integral bosses 18 engaged with opposite faces of the disc12hold` the disc against relative lateral movement.v The at engage-Ament: of the shoulders 1 9b with the rings and of the bosses 18 with thedisc 12 present eiective resistance .to bending stress 1n each rodintermediate its supports, under the centrifugal force due to rapidrevolution of the rod about the center of the shaft and obviates anystrains which might otherwise referred to several Y details ofmechanical construction and arrangement of parts, it will be understoodthat the invention is in no Way limited thereto exceptas may be pointedout in the appended claims.

I claim as my invention:

l. A rotor member for a disintegrating apparatus comprising a shaft, adisc fixed thereon, a circular row of disintegrator elements carried bysaid disc, rings carried by the ends of said disintegrator elements,each disintegrating element consisting of a bar extending through saiddisc provided with a boss intermediate its ends, the bosses of alternatebars engaging opposite faces of said disc. p

2, A rotor member for a disintegrating apparatus, comprising a shaft, adisc iixed thereon, a circular row of disintegrator e1ements carried bysaid disc and extending parallel to said shaft through said disc and toeach side thereof and rings carried at the ends of said disintegratorelements, each disintegrator element consisting of a bar having a fixedannular shoulder in its middle, the shoulders of alternate bars engagingopposite faces of said disc, and the ends of said bars each beingreduced in diameter to provide a radial shoulder engaged With theassociated ring.

3. A rotor member for a disintegrator apparatus, comprising a shaft, adisc fixed thereon, a. circular row of disintegrator bars carried bysaid disc and extending parallel to said shaft to each side of saiddisc, and rings carried by the ends of said bars, the disc and ringshaving holes in which said bars are engaged, the bars having integralbosses near their middle with the bosses of alternate bars engaged Withopposite faces of said disc, and said barsv having reduced ends engagedin the holes in the rings with the radial shoulders on the rods thusprovided engaged with the inner faces of said. rings.

In testimony that I claim the v,foregoing as my invention, I alix mysignatnrethie 13th day of May, A. D. 1927.
